Hi!
I am trying to make a map, in my project I have three datasets that I use for that. The problem is that at some point all my 3 datasets just cease to exists and I get this message when I try to open any of them:
"The object no longer exists"
Every time I open a new project and start with the work from the beginning, at some point I get this error again and again. Do you have any ideas how to avoid this?
